Definitions

• the present invention relates generally to an adjustable carrier assembly for a harness with adjustable shoulder straps.
• harness The simplest type of harness consists of a single band, which is worn by the user over one shoulder and across the back and chest respectively, to support the equipment at hip level. While this solution is sufficient for lighter equipment which is used seldom and during short periods of time, it is not adequate for professional us-ers who use the equipment for days on end. As the clearing saws are usually designed for use on one side of the user's body, the load will always be carried on one and the same shoulder, which could cause strain in the user's body in the long run.
• a better type of harness comprises one shoulder strap over each shoulder, a waist belt, a side strap, and a back plate to which all straps are connected. Quite often a shock-absorbing hip-pad is attached as well, against which a part of the equipment is sup-ported during use. The different straps may be adjusted to the size of the user.
• WO 2008/147256 discloses an adjustable harness for evenly distributing the weight of the equipment during use having a back plate comprising two rigid plate portions connected to each other to allow mutual rotation in a plane defined by the back plate.
• the connection is of a snap-fit type where a central boss on the upper plate portion fits into one of three holes on the lower plate portion. The holes are placed at different distances from the bottom of the lower plate portion correspond-ing to three distinct sizes of the back plate.
• disconnection and reconnection of the plate portions when changing the size is still quite cumbersome and the har-ness may only be adjusted between three distinct sizes.
• an object of the present invention is to provide an improved harness which facilitates individual size adjustment.
• the adjustable carrier assembly comprising a back plate and an interface plate including connections for shoulder straps, wherein the back plate comprises a coupling interface arranged to be removably connected to a corresponding coupling interface of the interface plate, wherein the coupling inter-face of the back plate is adapted to be connected to and disconnected from the cou-pling interface of the interface plate in an at least partially translational or linear movement which is substantially parallel to the back plate.
• the translational or linear movement of the interface plate with respect to the back plate allows for simpler and quicker adjustment of the size through a sliding motion. Additionally, the user will then no longer be required to disassemble and reassemble the back plate of the har-ness to change the size, contrary to what is known from the prior art.
• the coupling interface of the back plate com-prises two parallel raised ridges extending in a substantially longitudinal direction of the back plate, each having at least one overhanging flange and an L-shaped cross section with the flanges facing towards or away from each other, and the coupling interface of the interface plate comprises corresponding raised ridges, each having at least one overhanging flange and an L-shaped cross section with the flanges facing in the opposite direction of the corresponding flanges of the back plate, wherein the ridges are arranged such that when the back plate and the interface plate are aligned with each other and brought together in a translational or linear movement parallel to the ridges, the flanges are slid into locking engagement with each other to retain the interface plate on the back plate.
• the solution with the raised ridges and over-hanging flanges provides a secure connection between the interface plate and the back plate which ensures that the interface plate cannot be removed from the back plate in a direction perpendicular to the surface of the
• the back plate further comprises a plurality of locking projections arranged in two parallel rows extending in a direction parallel to the longitudinal extension of the back plate, wherein the interface plate comprises a pair of resilient locking tabs arranged to come into locking engagement with a cor-responding pair of locking projections to lock the position of the interface plate with respect to the back plate.
• the plurality of locking projections provides incremental size adjustment of the interface plate including the connections for shoulder straps with respect to the back plate along the length of the back plate, thus allowing the user to adapt the size on an individual level.
• the locking engagement ensures that the interface plate remains in place on the back plate during use.
• the resilient locking tabs are formed as ribs extending in a direction parallel to the ridges on the interface plate into an open-ing therein and comprise a main portion having a lateral projection adapted to engage the locking projections of the back plate, and a web portion connecting a distal end of the main portion to a central rib arranged between and at a distance from the locking tabs.
• the resilient locking tabs may easily be disengaged from the locking projections to allow removal of the interface plate from the back plate.
• the web portion acts to bias the resilient locking tab towards the locking engagement position.
• the central rib comprises a flange and has a T-shaped cross section
• the back plate comprises a central through-going slot arranged to receive the central rib when the back plate and the interface plate are aligned with each other and brought together in a translational or linear movement parallel to the ridges such that the flange is slid into locking engagement with the sur-face on the opposite side of the back plate.
• the T-shaped cross section of the central rib and flange provide additional retention of the interface plate on the back plate as well as guiding of the interface plate during insertion using the translational or linear movement.
• a proximal side of the locking projec-tions in an insertion direction of the interface plate has a bevelled or chamfered sur-face.
• a distal side of the resilient locking tabs in an insertion direction of the interface plate has a bevelled or chamfered surface. The bevelled or chamfered surfaces act to smoothly deflect the resilient locking tab later-ally when the interface plate is inserted into the back plate by translational or linear movement, such that the resilient locking tabs can move past the locking projections. Once the resilient locking tabs have passed one pair of locking projections, the former spring back into locking engagement with the subsequent pair of locking projections.
• leading and/or trailing edges of the flanges in an insertion direction of the interface plate has a bevelled or chamfered surface.
• the bevelled or chamfered surfaces provide a smooth sliding motion when inserting the interface plate onto the back plate.
